Application October 8, 1941, Serial No. 413,796

(Cl. ill-142) 6 Claims.

The present invention relates to a magnetic device and it particularly relates to a magnetc make-up board for holding and exposing articles to be photographed. l

In making up displays to be photographed, it is usually laboriously necessary to out out the devices and then to paste them in position upon a base or support and then to set them up where they may be studied prior to reproduction or photographing.

Usually the first set-up or arrangement is unsatisfactory, and frequently repeated rearrangements and revisions of the set-up are necessary to achieve the iinal desired result, with each setup either requiring a complete destruction of the earlier set-ups and the cutting out or formaton of new arrangements a time-consuming and laborlus repair even when the cut-outs or devices are applied by way of detachable cements upon a base.

It is among the objects of the present invention to provide an improved set-up or display board of the character above described, which will enable a ready adjustment of the design or set-up and e. more rapid progress from the nrst to the second or to subsequent studies prior to reproduction or photography without prolonged pasting and cutting operations and with assurance that the studies and displays may Toe made with a minioi esili and without expensive equipment or opparaims.,

slit/ill further objects and. advantages will from the more detailed description set iortli bclov, it being understood, however, that this more detailed description is given by way of illustration and explanation only, not by Way of limitation. since various changes therein may be made 'cy those sisillerl in the art without departing from the scope spirit ol the present inve` tion.

in accom the above objects, has been found mrsU satisfactory according to one crocodin o se invention provide a lease consisting l'ty ci .ro-vrs of a spaced high magnetic stre` gth alloys, numb i cc es of which may preferably arranged staggered, although closely rows over entire face of a base or icl to carry tire various displays..

*ne of cores directly project upon the board itself to receive tine removable displays.

0r there may Toe placed upon suoli magnetic "oase containing the staggered rows of magnetic cores, e removable sheet or hinged lcoarcl, prefer ably non-magnetic, forming a part or" the display unit.

Desiralnly the objects to be placed upon the board may consist ci thin out sheets of magnetic metals or alloys or thicker sheets of magnetic metal alloys which are to ce out, but the position of which is to be regulated.

The positioning, the staggering and alternation oi' the poles of these magnets over the entire face oi the board enables a ready adjustment, removal and replacement of the elements of the display w'th assurance that the designs or elements when placed upon the board will be held firmly in position without inadvertent misplacement or displacement during reproduction or photography.

In the drawing which shows several specific embodiments of the present invention by way of illustraton, but to the details of which the present invention is by no means restricted, since many changes and alternatives are possible,

Fig. l is a plan view of one form of a magnetic coard according to the present invention;

Fig. 2 is `a transverse sectional view upon the line 2--2 of Fig. l;

Fig. 3 is a fragmentary top plan View of an alternative construction;

Fig. 4 is a fragmentary transverse sectional view upon the line el-il of Fig. 3 showing alternative forms 0I" magnetic holders;

Fig. 5 is a side vieu.r of an alternative mounting construction; and

Fig. 6 is a fragmentary perspective view partly broken away, of another alternative arrangement.

Referring to there is a base-board in which have been cored a plurality of openings l and i2 in alternating rows. which openings are filled with the rows of permanent magnetic cores cylinders and l" of permanent :magnetic alloy sucia as an alur una nickel alloy, suoli as Alnico, or similar macys liar/ing high coercive force.

will ce noted. that the ecard is cut away or ermit the lished as indi ated i in z, to upper ends l? and Sil o the alternating rev/s and lll to project slightly above the recessed eleva faces oi 'the staggered as indicated ternating rows i l2 are oi so 'the projecting ends of north j :olcs smile the projecting' adjacent rot:7 will ce south lsoles.

'in the form shown Figs. l and 2, the site ends or" the are provided vf', handles 29, while the base of the board is covers by a sheet or plate 2 i lf desired in making up a display, sheet metal articles of a magnetic material or having a thin metallic backing or of laminated construction, one ci* the larnlnatlons consisting of magnetic material, may be placed upon the hoard as shown in Figs. l and 2 and arranged and rearranged and studied to give the desired effect which then may be photographed.

'I'he size and intensity of the magnets I3 and M are so regulated that the objects will be held firmly against inadvertent or accidental movement upon vthe board while at the same time deliberate application of the hands or manipulation will serve to displace or move the objects or remove them from the board.

Usually it is desired to cover the entire face of the board of Figs. 1 and 2 with a sheet of a nonmagnetic material such as paper or even a fabric, to give the desired backing, the fabric being suitably colored or carrying a mottled or other decorative background design.

By lifting or drawing ofi' the paper or fabric, which may be flexible or stiff, from the face of the board, the various objects which are held onto the board by the magnetic stress exerted by the magnets i3 and t6 through the paper or fabric will be simultaneously disengaged.

In this manner the applicant is able to obtain a most convenient display and utility board which y be widely utilized in the preparation of displays or utilized for photography or reproduction.

In Figs. 3 and 4 a different method of mounting the magnets is shown. As shown best in Fig. 4, the board has an upper face plate 22 having a recessed portion 23, and a raised rim 2&3.

The top of the rim 2d is ush with the upper faces 25 and the heads 26 of the pin or rod members 2l which extend downwardly through the openings 28 in said plate 22.

Upon the portion of the various rods 2l extending below the board 22 are positioned alternately the permanent magnetic alloy cylinders 29', as for example of Alnico, illustratively shown at the left or solenoids 292 illustratively shown at the right of Fig. 4. These cylinders or solenoids are in the staggered and alternating rows as described in connection with Fig. l. Each of the cylinders or solenoids'ZQ is held onto pins 2li by Ithe tightly fitting holed discs 3d. These pins 2l and their heads 26 may be of wrought iron or oi a soft steel. The iiux through the fiat heads 2t is eiective to retain even small armature blanks in position anywhere on the panel in the same manner as in the case of the embodiment of Figs. 1 and 2.

The lower ends of the pins 2l abut the baseboard 3l. The top board 22 and the baseboard 3i may be held together by the side boards 32.

In the arrangement shown in Fig. 5, the magnetic board 33, which may be of the construction shown either in Figs. 1 and 2 or the construction shown in Figs. 3 and 4, is pivotally supported at 3d upon the upright 35, which upright in turn is supported by the foot member 3S and the oblique member 3l.

The magnetic board may be swung into either vertical position as shown or into horizontal position, and the element 38 may be used as acatch to x the board 33 either in vertical or in horizontal position.

In the construction shown in Fig. 6, the mag.- netic board li@ which may be of the same construction as already described in connection with Figs. 1 and 2 or Figs. 3 and 4, has a cover il which is hinged to the base magnetic board d by the hinges d2.

Various articles may be arranged upon the covering board 4|, and they will be held in position by the magnetic force of the alternating and staggered rows of magnets 43 and 44. By lifting the cover 4l, these objects may then be displaced and removed from the board.

Although the baseboard l0 of Fig. 1, or the elements 22, 3i and 32 oi Fig. 4 may be made of any non-magnetic material, they have been pre1'- erably made of molded plastic materials such as molded Bakelite or cellulose acetate plastics such as Tenite.

The construction as shown is particularly suitable for the arrangement of various types of letters or designs or magnetic materials, and after the desired arrangement has been made, the arrangement may be readily photographed. Where non-magnetic sheets are to be held upon the board.' strips of iron or steel may be employed to hold these sheets upon the board.

Many other changes could be effected in the particular features of the magnetic sign apparatus designed, and in methods of operation set forth, and in specific details thereof, without substantially departing from the invention intended to be defined in the claims, the speciiic description herein merely serving to illustrate certain elements by which, in one embodiment, the spirit of the invention may be eiectuated.
